Tips/Tricks
crumble will keep for about 5 days in the fridge... BUT why would you
you can use this recipe base for any crumble, you may just need to edit the sugar quantity for certain sweeter fruits but then again a tropical fruit crumble seems kinda weird
stay away from rhubarb leaves, in case you didn't know they contain high levels of oxalic acid. You would need to eat a reasonable amount for it to be harmful but lets not experiment on that one
